A Physics Professor at Trinity College has warned the nation that the sun is "very very hot."

Peter Gallagher, who teaches at Trinity, was speaking on 98FM about Mercury orbiting the sun tonight.

But he bizarrely stated the obvious, before going on to describe the earth as a "rocky thing."

Professor Gallagher said: "It just shows you that there's a planet moving, a planet like our own and this planet happens to be much closer to the sun.

"It's not a place you'd want to live, it's very very hot. But yano it's great for people to actually see the sun in a telescope for starts, this enormous blob of hot gas and then they see this rocky thing.

"We live on something like that little rocky thing that's rotating around a star in the middle of space."

So there you go lads, don't go to the sun, you might get sunburned.

If you do fancy seeing the planet Mercury, head down to Trinity College before 6pm this evening and take a look.
